European SQL Server 2019 Hosting :: Search A String Entire Database (SQL Server)

clock October 21, 2022 07:02 by author Peter

In this tutorial, I will tell you about How to search a string entire database on SQL Server.

--USE DATABASE_NAME
DECLARE @SearchStr nvarchar(100) = 'Class VIII'
DECLARE @Results TABLE (ColumnName nvarchar(370), ColumnValue nvarchar(3630))

SET NOCOUNT ON

DECLARE @TableName nvarchar(256), @ColumnName nvarchar(128), @SearchStr2 nvarchar(110)
SET  @TableName = ''
SET @SearchStr2 = QUOTENAME('%' + @SearchStr + '%','''')

WHILE @TableName IS NOT NULL

BEGIN
    SET @ColumnName = ''
    SET @TableName =
    (
        SELECT MIN(QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME))
        FROM     INFORMATION_SCHEMA.TABLES
        WHERE         TABLE_TYPE = 'BASE TABLE'
            AND    QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME) > @TableName
            AND    OBJECTPROPERTY(
                    OBJECT_ID(
                        QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME)
                         ), 'IsMSShipped'
                           ) = 0
    )

    WHILE (@TableName IS NOT NULL) AND (@ColumnName IS NOT NULL)

    BEGIN
        SET @ColumnName =
        (
            SELECT MIN(QUOTENAME(COLUMN_NAME))
            FROM     INFORMATION_SCHEMA.COLUMNS
            WHERE         TABLE_SCHEMA    = PARSENAME(@TableName, 2)
                AND    TABLE_NAME    = PARSENAME(@TableName, 1)
                AND    DATA_TYPE IN ('char', 'varchar', 'nchar', 'nvarchar', 'int', 'decimal')
                AND    QUOTENAME(COLUMN_NAME) > @ColumnName
        )

        IF @ColumnName IS NOT NULL

        BEGIN
            INSERT INTO @Results
            EXEC
            (
                'SELECT ''' + @TableName + '.' + @ColumnName + ''', LEFT(' + @ColumnName + ', 3630)
                FROM ' + @TableName + ' (NOLOCK) ' +
                ' WHERE ' + @ColumnName + ' LIKE ' + @SearchStr2
            )
        END
    END
END


For example, I will search the above mentioned string then the sample output is as follows:

European SQL Server 2019 Hosting :: ANSI_NULLS In SQL Server

clock October 18, 2022 08:53 by author Peter

ANSI_NULLS define the comparison rule for NULL values in SQL Server.
 
When SET ANSI_NULLS is OFF, the Equals (=) and Not Equal To (<>) comparison operators do not follow the ISO standard. A SELECT statement that uses WHERE column_name = NULL returns the rows that have null values in column_name.
 
Example

But when SET ANSI_NULLS is ON, a SELECT statement that uses WHERE column_name = NULL returns zero rows even if there are null values in column_name.

European SQL Server 2019 Hosting :: SQL Server Primary Keys

clock October 14, 2022 08:51 by author Peter

Introduction
Hope you're familiar with the concepts of what's a primary key in a relational database management system like SQL Server. But, you need more details to better understand it, or you need some review or refresher for yourself, you have come to the right place.

This article will discuss a primary key, entity integrity, primary key constraint, composite keys, and the benefits of a primary key.

Let's get started.

What's A Primary Key?

A primary key is a logical concept where a column or field uniquely identifies each record inside a database table. Moreover, it has multiple attributes: it must not be null, and it must be unique.

Easy to remember, right? But if you're curious, we'll test and see what will happen when we try to pass a NULL and duplicate value in a primary column in the latter part of the article.
What's Entity Integrity?

Entity integrity is a rule for practical database construction, and this practice is widely used. It is a process of enforcing the primary key for each table in a database.

Therefore, it is implemented to uniquely identify each row inside the table by specifying a primary key inside our database table.
What's a Primary Key Constraint?

A primary key constraint is a restriction that basically ensures entity integrity.

Note: Unique constraint also ensures entity integrity.
Benefits of Primary Key and Entity Integrity

Proper usage and selection of a primary key and maintaining entity integrity prevent duplicate records and other issues that would indirectly compromise the integrity of the database.

Things to Remember About Primary Keys
    A primary key column cannot have NULL values.
    A primary key column cannot have duplicate values.
    A table can have only one primary key constraint.
    When multiple columns are used as primary keys, they are called composite keys.
    It is good to remember that a primary key is the default clustered index if a clustered index on the table does not exist.

Composite Keys
Now, you might ask why I see multiple primary keys in one table? Those are called composite keys.

Composite keys use two or more fields from a table to create a unique value.

Therefore, it guarantees uniqueness only when combined columns, but they don't guarantee uniqueness individually.

Creating A Primary Key on A Table
Let's show how we can define a column as a primary key.
CREATE TABLE EMPLOYEE(
[Id] int NOT NULL IDENTITY(1,1),
[FirstName] nvarchar(50),
[LastName] nvarchar(50),
[Age] int,
PRIMARY KEY (Id))


In the code sample above, we have seen that using the PRIMARY KEY then passing the column Id, we have defined the primary key of the EMPLOYEE table.

Let's try to see the result below.

Add a Primary Key on A Table
Let's recreate the table from the previous example, but we will not create the primary key.
We will create a primary key after we have created the table.
Let's try to see the code sample below.
IF EXISTS (SELECT * FROM  [INFORMATION_SCHEMA].[TABLES] WHERE [TABLE_NAME] ='EMPLOYEE')
BEGIN
    DROP TABLE EMPLOYEE;
END
GO
BEGIN
CREATE TABLE EMPLOYEE(
    [Id] int NOT NULL IDENTITY(1,1),
    [FirstName] nvarchar(50),
    [LastName] nvarchar(50),
    [Age] int);
END
GO
BEGIN
ALTER TABLE EMPLOYEE ADD PRIMARY KEY(Id);
END

Just a note, if you have removed the IDENTITY (1,1), everything will still be good and have no errors because it's an auto-incrementing column.

Although these two are used together, there's no requirement when defining a primary key column that it needs to be an identity column.

Let's try to see an example below.
IF EXISTS (SELECT * FROM  [INFORMATION_SCHEMA].[TABLES] WHERE [TABLE_NAME] ='EMPLOYEE')
BEGIN
    DROP TABLE EMPLOYEE;
END
GO
BEGIN
CREATE TABLE EMPLOYEE(
    [Id] int NOT NULL,
    [FirstName] nvarchar(50),
    [LastName] nvarchar(50),
    [Age] int);
END
GO
BEGIN
ALTER TABLE EMPLOYEE ADD PRIMARY KEY(Id);
END

Again, another note, if we have forgotten the NOT NULL that makes the Id column nullable, it will give you an error.

You'll probably see an error like this
    "Cannot define a PRIMARY KEY constraint on nullable column in table 'EMPLOYEE.'"

Let's try to see an example below.
IF EXISTS (SELECT * FROM  [INFORMATION_SCHEMA].[TABLES] WHERE [TABLE_NAME] ='EMPLOYEE')
BEGIN
    DROP TABLE EMPLOYEE;
END
GO
BEGIN
CREATE TABLE EMPLOYEE(
    [Id] int, -- NOT NULL REMOVED FOR YOU TO SEE THE ERROR MESSAGE
    [FirstName] nvarchar(50),
    [LastName] nvarchar(50),
    [Age] int);
END
GO
BEGIN
ALTER TABLE EMPLOYEE ADD PRIMARY KEY(Id);
END


Let's try to see the result below.


Delete Primary Key on A Table
In this section, let's try to recreate the table again, but after creating the table, let's make a primary key with the name of [PK_ON_EMPLOYEE_TABLE].
The reason for giving the primary key a custom name is so we won't have a hard time knowing its name when we need to drop the primary key.

Let's try to see the example below.

PRINT 'STEP 0. DROP EMPLOYEE TABLE IF EXISTS'

IF EXISTS (SELECT * FROM  [INFORMATION_SCHEMA].[TABLES] WHERE [TABLE_NAME] ='EMPLOYEE')
BEGIN
    PRINT 'STEP 0.1 DROPPING EMPLOYEE TABLE'
    DROP TABLE EMPLOYEE;
END
GO

PRINT 'STEP 1. CREATE THE TABLE'

BEGIN
CREATE TABLE EMPLOYEE(
    [Id] int NOT NULL IDENTITY(1,1),
    [FirstName] nvarchar(50),
    [LastName] nvarchar(50),
    [Age] int);
PRINT 'STEP 1.1 EMPLOYEE TABLE CREATED'
END
GO

BEGIN
PRINT 'STEP 2. EMPLOYEE TABLE ADDING PRIMARY KEY [PK_ON_EMPLOYEE_TABLE]'
ALTER TABLE EMPLOYEE ADD CONSTRAINT [PK_ON_EMPLOYEE_TABLE] PRIMARY KEY(Id);
END
GO

BEGIN
PRINT 'STEP 3. EMPLOYEE TABLE REMOVING THE PRIMARY KEY'
ALTER TABLE EMPLOYEE
DROP CONSTRAINT [PK_ON_EMPLOYEE_TABLE];
END

Inserting NULL values into Primary Key Column
This obviously will show an error because we're violating the primary key constraint.
Still, we'll see how the SQL Server will react when inserting NULL values out of curiosity.

Let's try to see an example below.
IF EXISTS (SELECT * FROM  [INFORMATION_SCHEMA].[TABLES] WHERE [TABLE_NAME] ='EMPLOYEE')
BEGIN
    DROP TABLE EMPLOYEE;
END
GO
BEGIN

CREATE TABLE EMPLOYEE(
    [Id] int NOT NULL,
    [FirstName] nvarchar(50),
    [LastName] nvarchar(50),
    [Age] int);
END
GO

BEGIN
ALTER TABLE EMPLOYEE ADD PRIMARY KEY(Id) ;
END
GO

BEGIN
--LET'S INSERT NULL value and expect an error
INSERT INTO [dbo].[EMPLOYEE] ([Id],[FirstName],[LastName],[Age])
VALUES
(NULL, 'Jin', 'Necesario', 100)
END
GO


Let's try to see the result below.

Inserting Duplicate Values into Primary Key Column
Again, this will obviously show an error because we're violating the primary key constraint. Still, we'll see how the SQL Server will react when inserting duplicate values out of curiosity.

Let's try to see an example below.
IF EXISTS (SELECT * FROM  [INFORMATION_SCHEMA].[TABLES] WHERE [TABLE_NAME] ='EMPLOYEE')
BEGIN
    DROP TABLE EMPLOYEE;
END
GO
BEGIN

CREATE TABLE EMPLOYEE(
    [Id] int NOT NULL,
    [FirstName] nvarchar(50),
    [LastName] nvarchar(50),
    [Age] int);
END
GO

BEGIN
ALTER TABLE EMPLOYEE ADD PRIMARY KEY(Id) ;
END
GO

BEGIN
--LET'S INSERT SAME Id value of 1 and expect an error
INSERT INTO [dbo].[EMPLOYEE] ([Id],[FirstName],[LastName],[Age])
VALUES
(1, 'Jin', 'Necesario', 100),
(2, 'Vincent','Necesario', 100),
(1, 'Jin Vincent','Necesario', 100)
END
GO


Let's try to see the result below.

European SQL Server 2019 Hosting :: Easily Improve Your .NET Code Quality With NDepend

clock October 4, 2022 08:31 by author Peter

NDepend is a static code analyzing tool which will help us to improve the source code quality by reducing the issues in our code. Patrick Smacchia introduced NDepend in 2007. This tool will likely find hundreds or even thousands of issues affecting our code base. Stopping all work to try and fix all issues for weeks would be quite unproductive. This is the only tool that proposes to focus on progress from a baseline. The tool estimates the technical debt evolution since the baseline.

Recent code smells that should be fixed before committing any code to source control are highlighted in the code just edited. NDepend is the only .NET tool that can tell the developer that over the past hour, the code just written has introduced debt that would cost for example about 30 minutes should it have to be repaid later. Knowing this, the developer can fix the code before even committing it to the source control.

In this post, we can see all the steps to download and install NDepend in our Windows machine and analyze our source code.  

Please refer to NDepend official site for more information.  

This tool can be useful for developers, architects, and DevOps people. This is integrated with all Visual Studio versions from 2010 to 2022. All features are available side-by-side with Visual Studio Code and Rider thanks to the standalone app VisualNDepend.exe

We can use this tool to analyze .NET 6.0, .NET 5.0, (and soon .NET 7), .NET Core and other versions, .NET Fx 4.x, ASP.NET Core, Blazor, Xamarin, Unity and UWP applications.
Download and Install NDepend on Windows machine.

NDepend is giving a 14-day fully functional trial version. We can use this trial version to explore all the features and once we are satisfied, we can buy the professional version.

We can extract the Zip file in any folder except '%ProgramFiles%\NDepend'. This might provoke problems because of Windows protection.

The Zip file includes four main executable files. 
NDepend.Console.exe is a console application which is used for registering and unregistering the license of NDepend.  It can also be used from your CI/CD to generate HTML+js reports about the health of your code base (see some sample reports here)


NDepend.PowerTools.exe is another console application which will help us to perform various operations via command line. Notice that power-tools are Open-Source and relies on the NDepend.API.

Currently, this tool has 18 various usages. We can choose any of these choices and hit enter key to continue.

I have chosen ‘r’.  This power tool analyzed the .NET 5.0 and 6.0 public APIs.  

NDepend.VisualStudioExtension.Installer.exe is an installer file. This file will install the NDepend extension in our Visual Studio version.

I am using Visual Studio 2022 on my machine. We can choose our respective versions.

You must agree to the license terms. It may take some time to complete the entire extension installation.
After successful installation, we can open Visual Studio. 

We can see the new extension under the Extensions menu. We can choose the New Project option from the menu.

We can give a valid Project Name. We are going to analyze one .NET 6.0 project. I have already written one project for JWT Authentication. We can use this project to analyze with NDepend.

We can click Add VS Solution or Project button and add our existing .NET 6.0 project. 

We can choose our existing project by clicking on the Browse button. We can also select multiple projects by clicking on the Check All button. It will select all the compatible projects that exist in our system. 


We can click the play button on the left top corner to start the analysis.  
After analysis (it just takes a few seconds), we can see new menus in the NDepend toolbar. 

We can click Dashboard option. 


We can see the elaborated analysis in the dashboard page. Total 355 lines in our project. Among the 355 lines, 24 lines are comments. We got an exceptionally good A rating. Still there are 5 rules violation and 15 issues in the code. 

We can click on 5 violated rules and see the details below.

Same way, we can click on the single issue with priority High and see more details of the issue.
Dependency Graph is another option in the tool. We can choose this option from the menu. See a 6 minutes intro video about the graph on youtube here.

Dependency Matrix is another good option in this tool. See a 5 minutes intro video about the matrix on youtube here.


Code Metrics View is also one of the good features in this tool. See a 4 minutes intro video about this metric view on youtube here.


VisualNDepend.exe is a standalone tool which can be used to analyze the .NET projects without Visual Studio.


We can create a new project or open an existing NDepend project and analyze using this Visual tool.

All the features like Dashboard, Dependency Graph, Dependency Matrix, and Code Matrics View are available in this tool as well.

Once we have bought the professional license, we can update the license using  NDepend Console tool.  

Conclusion

In this post, we have seen the introduction of NDepend tool which is a static code analysis tool that can be used for improving the code quality of our .NET or .NET Core source code. We have installed the NDepend extension in Visual Studio 2022 and analyzed one existing .NET 6.0 project using this tool. We have seen various features like Dashboard, Dependency Graph, Dependency Matrix, and Code Matrics View in this tool. I have just given an introduction about NDepend tool in this post. We can see more information about this tool in an upcoming post later. Please feel free to give your valuable feedback about this article.

European SQL Server 2019 Hosting :: Find Procedure Names And Same Parameters Name Used In Procedure

clock September 28, 2022 10:29 by author Peter

We get a procedure list with the help of DMV like " Sys.objects & sys.parameters"

USE [SqlBank]

SELECT s.NAME StoreProcedure, p.NAME Parameter FROM SYS.PARAMETERS p
JOIN SYS.OBJECTS s on p.object_id=s.object_id
WHERE TYPE='P'
ORDER BY p.NAME


From the above query, we get Procedure name with parameters

European SQL Server 2019 Hosting :: T-SQL - Pivoting And Unpivoting Data

clock September 23, 2022 09:32 by author Peter

When SELECTing information from the table(s), we mostly ask for grouped data. Grouping allows us to retrieve statistical data by some columns. Grouping is very important, but sometimes it is not just enough to “generate” final information.

Sometimes we need to rotate one of the columns to be as a row without changing the result of grouped data. Long story short, transforming data from a state of rows to a state of columns is called Pivoting.

PS: All examples use Adventurework2019.

Simple example without pivot: (classical grouping)
SELECT
  SalesOrderID
, SpecialOfferID
, SUM(UnitPrice) as TotalSum
  FROM Sales.SalesOrderDetail AS SOD
  GROUP BY SalesOrderID, SpecialOfferID

In the above example, we get data grouped by SalesOrderId and SpecialOfferId. Say your manager asked for the same data but he wants to see SpeciallOfferId in the columns. So from the above example, you will have columns like [1], and [2]. The main focus is SpecialOfferId and we need to somehow rotate the column to be not a column but a row.

T-SQL provides a special table operator to implement it: PIVOT.

Before writing PIVOT, let’s see what you need to know about the internal implementation of PIVOT. You should identify 3 elements:

    What do you want to see on rows?
    What do you want to see on columns?
    What type of information should be rendered in the intersection of these columns and rows ( mostly it is your aggregate column)

Here is the syntax for implementing it,

As we learned from the article, Common Table Expression’s (CTE) use cases wider than Derived Tables and now we will implement PIVOT exactly with CTE.

WITH CTE
AS
(SELECT SOd.SalesOrderID, Sod.SpecialOfferID, UnitPrice
  FROM Sales.SalesOrderDetail AS SOD)
  SELECT SalesOrderId, [1],[2] FROM CTE
  PIVOT(SUm(UnitPrice) FOR SpecialOfferId IN ([1],[2])) AS PVT

As you can see, PIVOT is a special table expression and as a complex combination, it defines the aggregate column for the spread column. Before switching to UNPIVOT, we need to understand some limitations of PIVOT:

    We can use only one aggregate with PIVOT
    The IN clause of the PIVOT operator accepts a static list of spreading values. You need to type them manually without any magic technique.
    No way to use COUNT(*), use classical COUNT(<column name>)

Unpivot is a reverse operation for you PIVOT. If you have any table generated by u PIVOT, you can reverse this table to the “original one” with UNPIVOT.

Let’s use our query with some modifications to create a table that will store all PIVOTted data.
WITH CTE
AS
(SELECT SOd.SalesOrderID, Sod.SpecialOfferID, UnitPrice
  FROM Sales.SalesOrderDetail AS SOD)
  SELECT * INTO MyPivottedTable FROM CTE
  PIVOT(SUm(UnitPrice) FOR SpecialOfferId IN ([1],[2])) AS PVT


The above query will store all information inside new created MyPivottedTable table.

Now it is time for our magic UNPIVOT to ”restore” information to its original.
SELECT SalesOrderID,SpecialOfferID, UnitPrice
 FROM MyPivottedTable
 UNPIVOT(UnitPrice FOR SpecialOfferId IN ([1],[2])) AS UNPVT


Here is the response:

European SQL Server 2019 Hosting :: SQL INTERSECT And EXCEPT Operator

clock September 13, 2022 09:19 by author Peter

These two operators EXCEPT and INTERSECT have been introduced since SQL Server 2005 and these two returns distinct or unique values by comparing the results of two queries.

Moreover, these operators do have rules for combining result sets just like other operators like UNION and we’ll also discuss it.

That’s why in this article we’ll be showing how we can use these two operators and understand their differences.

What is INTERSECT Operator?
Fundamentally, INTERSECT operator combines two or more queries and returns unique rows or records that are the outcomes of both left and right queries.

Then it removes duplicate records as the final result set.

INTERSECT Syntax
--INTERSECT Syntax
query_expression
INTERSECT
query_expression


It is similar to the UNION operator, that’s why both queries must have the same number and order of columns, and the column data type should be the same.

Furthermore, if these rules aren’t followed an error will occur like failing conversion of data and an equal number of expressions error.

INTERSECT Operator Example
Before we can see examples, let’s try to create a table first with some data in it.
DECLARE @TBLDOGS TABLE (Id int, DogBreed nvarchar(50))
DECLARE @TBLDOG_OWNERS TABLE (Id int, OwnersName nvarchar(50),
DogBreed nvarchar(50))

INSERT INTO @TBLDOGS (Id, DogBreed)
VALUES
(1, 'German Shepherd'),
(2, 'Labrador Retriever'),
(3, 'Golden Retriever'),
(4, 'Poodle'),
(5, 'French Bulldog')

INSERT INTO @TBLDOG_OWNERS (Id, OwnersName, DogBreed)
VALUES
(1, 'Bruce Wayne', 'German Shepherd'),
(2, 'Lex Luthor', 'Golden Retriever'),
(3, 'Vandal Savage', 'Dobermann'),
(4, 'Maxwell Lord', 'Dachshund'),
(5, 'Simon Stagg ', 'Poodle'),
(6, 'Elon Musk', 'German Shepherd')

SELECT * FROM @TBLDOGS
SELECT * FROM @TBLDOG_OWNERS


Output


OK, so everything has been set up. Let’s show how we can use the INTERSECT operator.
SELECT DogBreed FROM @TBLDOGS
INTERSECT
SELECT DogBreed FROM @TBLDOG_OWNERS


Output

As you can see, in our example we have two tables @TBLDOGS and @TBLDOG_OWNERS. Going to the data of the two tables, @TBLDOGS have German Shepherd, Labrador Retriever, Golden Retriever, Poodle, and French Bulldog.

While @TBLDOG_OWNERS have German Shepherd, Golden Retriever, Dobermann, Dachshund, Poddle, and German Shepherd.

The intersection of the two tables resulted in a German Shepherd, Golden Retriever, and Poodle.

What is EXCEPT Operator?
Fundamentally, EXCEPT operator subtracts a query result set from another query result set.

In other words, it returns unique rows or records from the left query that doesn’t appear or are not found on the right query.

EXCEPT Syntax
--EXCEPT Syntax
query_expression
EXCEPT
query_expression


Moreover, both queries must have the same number and order of columns, and the column data type should be the same.

Furthermore, if these rules aren’t followed an error will occur like failing conversion of data and an equal number of expressions error.

EXCEPT Operator Example

Data about dogs from the previous example, we’re still going to use here.

To lessen confusion I’ll be posting again the data sample of dogs.
DECLARE @TBLDOGS TABLE (Id int, DogBreed nvarchar(50))
DECLARE @TBLDOG_OWNERS TABLE (Id int, OwnersName nvarchar(50),
DogBreed nvarchar(50))

INSERT INTO @TBLDOGS (Id, DogBreed)
VALUES
(1, 'German Shepherd'),
(2, 'Labrador Retriever'),
(3, 'Golden Retriever'),
(4, 'Poodle'),
(5, 'French Bulldog')

INSERT INTO @TBLDOG_OWNERS (Id, OwnersName, DogBreed)
VALUES
(1, 'Bruce Wayne', 'German Shepherd'),
(2, 'Lex Luthor', 'Golden Retriever'),
(3, 'Vandal Savage', 'Dobermann'),
(4, 'Maxwell Lord', 'Dachshund'),
(5, 'Simon Stagg ', 'Poodle'),
(6, 'Elon Musk', 'German Shepherd')

SELECT * FROM @TBLDOGS
SELECT * FROM @TBLDOG_OWNERS


Output


OK, so everything has been set up. Let’s show how we can use the EXCEPT operator.

SELECT DogBreed FROM @TBLDOGS
EXCEPT
SELECT DogBreed FROM @TBLDOG_OWNERS

SELECT DogBreed FROM @TBLDOG_OWNERS
EXCEPT
SELECT DogBreed FROM @TBLDOGS


Output

Going to the data of the two tables, the EXCEPT operator resulted differently and it makes a significant difference because of what is on the left table.
Moreover, as we change the left table we have different results.
Moreover, from the example above the first result, the left query is the @TBLDOGS while the right query is the @TBLDOG_OWNERS.
While the second result, the left query is the @TBLDOG_OWNERS while the right query is the @TBLDOGS.
Let’s see the difference between EXCEPT and INTERSECT operators in the next section.

Difference Between INTERSECT and EXCEPT Operators


Remember that the Intersect operator uses an intersection that takes rows from both result sets that are common in both.

While the Except operator takes rows from the left result set but excludes the right result set that isn’t found.

Conclusion

In this article, we have learned how to use the SQL Server’s INTERSECT and EXCEPT operators and have seen some examples to understand these operators.
Moreover, we didn’t forget to show the difference between the two.
I hope you have enjoyed this article, as I enjoyed it while writing.
Till next time, Happy programming! Cheers! And Thank you!
